Sacrifice

[fable]

In 4 games on impossible I've found Sacrifice in Freedom Island 2 times, once later in Demonis, and once nowhere (I've restarted it in Demonis, as it was a must-have for the no-buy strategy, couldn't get to elven lands without it)

In my current game I've checked all of Demonis, most of Elven land and Land of the Dead, and still missing Resurrect and Target.

Sacrifice is not even a high-end spell like Armageddon. While it's a nice spell, if you're not playing no-buy or no-loss game, it's just a spell.

I doubt anyone uses cheats, but there are neat tricks that can get you through difficult times. There're tricks to beat the giant turtle without big armies. You can collect a lot of cash in Freedom Island without killing anything and buy the map with cash. With that you can enter the dwarven lands, and from there you can lure the enemies out of corridors and sneak past them, even into Demonis. That gives you access a lot of traders with possible Sacrifice spell, practically without killing anything.
